Even though China has grown at an absolutely furious pace for over the last decade, as of 2013, in terms of gross domestic product (GDP), The United States is the largest economy in the world by far. China trails the US at No. 2, and is widely acknowledged to be on track to take over as the world's largest economy by 2023, though they still have a ways to go in terms of GDP to oust the US from the top spot.

Why do economists think China will overtake the US as the world's largest economy? It's simple — Asian industrialization has been outpacing Western economies for years, and is expected to continue to do so over the next several decades. Consider the simple fact that the average worker in China works 2,307 hours per year while the average American worker puts in 1,790 hours per year.

Once China achieves the top spot in world economies, it cannot rest on its laurels. Major economists predict that India will take over China for the top position by 2048. Once again Asian industrialization will continue to grow by leaps and bounds, while Western cultures begin to slip further behind. How can the US maintain its position at the top? Work longer hours and take fewer holidays! (Yay?)

Of course this is all just speculation at this point based on recent worldwide trends. The U.S. and Europe can turn things around if they pick up their pace, change their policies, and stop outsourcing work to China and India. Let's take a look at the 10 Largest Economies in the World according to each country's GDP.
